Hello Like Matthias (http://gmod.827538.n3.nabble.com/Fatal-Error-while-uploading-a-File-with-spe...) I can't upload a file with special characters. My test file is : Frédéric.txt The database itself seems to be ok, I can see that the insertion is ok in "history_dataset_association" : id history_id dataset_id create_time update_time copied_from_history_dataset_association_id hid name info 328 1 330 2017-03-01 08:13:56 2017-03-01 08:14:05 NULL 293 Frédéric.txt uploaded txt file 1 line But until I change Frédéric.txt to Frederic.txt within the name column, my history is broken. Errors are the same as described by Matthias. galaxy.web.framework.decorators ERROR 2017-03-01 09:14:18,321 Uncaught exception in exposed API method: Traceback (most recent call last): File "/softs/bioinfo/galaxy-prod/lib/galaxy/web/framework/decorators.py", line 284, in decorator rval = _format_return_as_json( rval, jsonp_callback, pretty=trans.debug ) File "/softs/bioinfo/galaxy-prod/lib/galaxy/web/framework/decorators.py", line 317, in _format_return_as_json json = safe_dumps( rval, **dumps_kwargs ) File "/softs/bioinfo/galaxy-prod/lib/galaxy/util/json.py", line 67, in safe_dumps dumped = json.dumps( obj, allow_nan=False, **kwargs ) File "/usr/local/lib/python2.7/json/__init__.py", line 251, in dumps sort_keys=sort_keys, **kw).encode(obj) File "/usr/local/lib/python2.7/json/encoder.py", line 209, in encode chunks = list(chunks) File "/usr/local/lib/python2.7/json/encoder.py", line 431, in _iterencode for chunk in _iterencode_list(o, _current_indent_level): File "/usr/local/lib/python2.7/json/encoder.py", line 332, in _iterencode_list for chunk in chunks: File "/usr/local/lib/python2.7/json/encoder.py", line 390, in _iterencode_dict yield _encoder(value) UnicodeDecodeError: 'utf8' codec can't decode byte 0xe9 in position 2: invalid continuation byte I have read a lot of threads about this kind of error (mostly from stackoverflow) It is related to Galaxy or it's related to my python installation ? For a production server, it means that I will have to update manually the database each time a user try to upload such a file (find his id, find the broken history and the file name to correct !) I'm running Galaxy 17.01 with a mysql (5.7.11-4, UTF-8) database. I've modified lib/galaxy/datatypes/binary.py (for XLS datatypes) and lib/galaxy/jobs/runners/__init__.py (truncate the job name for PBS-PRO) # On branch release_17.01 # Your branch is ahead of 'origin/release_17.01' by 3 commits. # # Changed but not updated: # (use "git add <file>..." to update what will be committed) # (use "git checkout -- <file>..." to discard changes in working directory) # # modified: lib/galaxy/datatypes/binary.py # modified: lib/galaxy/jobs/runners/__init__.py Thanks in advance!
